WebPrinciple of the Jendrassik Grof method: Definition. The principle of this method is a classic diazo reaction which combines sulfanilic acids in dilute HCL with sodium nitrite to form nitrous acid. Nitrous acid forms the basis for the diazized sulfanilic acid. Direct bilirubin combines with the sulfanilic acid to form a blue color at a alkaline pH. Web1. SUMMARY OF TEST PRINCIPLE AND CLINICAL RELEVANCE . The DxC800 uses a timed-endpoint Diazo method (Jendrassik-Grof) to measure the concentration of total bilirubin in serum or plasma. In the reaction, bilirubin reacts with diazo reagent in the presence of caffeine, benzoate, and acetate as accelerators to form azobilirubin.
